WordPress Plugin Development Workflow

Overview

Specialized workflow for creating WordPress plugins with proper architecture, hooks system, admin interfaces, REST API endpoints, and security practices. Now includes WordPress 7.0 features for modern plugin development.

WordPress 7.0 Plugin Development

Key Features for Plugin Developers

1. Real-Time Collaboration (RTC) Compatibility

   • Yjs-based CRDT for simultaneous editing
   • Custom transport via sync.providers filter
   • Requirement : Register post meta with show_in_rest => true

2. AI Connector Integration

   • Provider-agnostic AI via wp_ai_client_prompt()
   • Settings > Connectors admin screen
   • Works with OpenAI, Claude, Gemini, Ollama

3. Abilities API

   • Declare plugin capabilities for AI agents
   • REST API: /wp-json/abilities/v1/manifest
   • MCP adapter support

4. DataViews & DataForm

   • Modern admin interfaces
   • Replaces WP_List_Table patterns
   • Built-in validation

5. PHP-Only Blocks

   • Register blocks without JavaScript
   • Auto-generated Inspector controls

        return;
    }
    
    $content = strip_tags($post->post_content);
    if (empty($content)) {
        return;
    }
    
    // Build prompt - direct string concatenation for input

    // Set temperature for consistent output
    $result->using_temperature(0.3);
    $summary = $result->generate_text();
    
    if ($summary && !is_wp_error($summary)) {
        update_post_meta($post_id, '_ai_summary', sanitize_textarea_field($summary));
    }
}

Abilities API Registration

// Register ability categories on their own hook
add_action('wp_abilities_api_categories_init', function() {
    wp_register_ability_category('content-creation', [
        'label' => __('Content Creation', 'my-plugin'),
        'description' => __('Abilities for generating and managing content', 'my-plugin'),
    ]);
});

// Register abilities on their own hook
add_action('wp_abilities_api_init', function() {
    wp_register_ability('my-plugin/generate-summary', [
        'label' => __('Generate Summary', 'my-plugin'),
        'description' => __('Creates an AI-powered summary of content', 'my-plugin'),
        'category' => 'content-creation',
        'input_schema' => [
            'type' => 'object',
            'properties' => [
                'content' => ['type' => 'string'],
                'length' => ['type' => 'integer', 'default' => 2]
            ],
            'required' => ['content']
        ],
        'output_schema' => [
            'type' => 'object',
            'properties' => [
                'summary' => ['type' => 'string']

        'execute_callback' => 'my_plugin_generate_summary_cb',
        'permission_callback' => function() {
            return current_user_can('edit_posts');
        }
    ]);
});

// Handler callback
function my_plugin_generate_summary_cb($input) {
    $content = isset($input['content']) ? $input['content'] : '';
    $length = isset($input['length']) ? absint($input['length']) : 2;
    
    if (empty($content)) {
        return new WP_Error('empty_content', 'No content provided');
    }
    
    if (!function_exists('wp_ai_client_prompt')) {
        return new WP_Error('ai_unavailable', 'AI not available');
    }
    
    $prompt = sprintf('Create a %d-sentence summary of: %s', $length, substr($content, 0, 2000));
    
    $result = wp_ai_client_prompt($prompt)
        ->using_temperature(0.3)
        ->generate_text();
    
    if (is_wp_error($result)) {
        return $result;
    }
    
    return ['summary' => sanitize_textarea_field($result)];
}

PHP-Only Block Registration

// Register block entirely in PHP (WordPress 7.0)
// Note: For full PHP-only blocks, use block.json with PHP render_callback

// First, create a block.json file in build/ or includes/blocks/
// Then register in PHP:

// Simple PHP-only block registration (WordPress 7.0+)
if (function_exists('register_block_type')) {
    register_block_type('my-plugin/featured-post', [
        'render_callback' => function($attributes, $content, $block) {
            $post_id = isset($attributes['postId']) ? absint($attributes['postId']) : 0;
            
            if (!$post_id) {
                $post_id = get_the_ID();
            }
            
            $post = get_post($post_id);
            
            if (!$post) {
                return '';
            }
            
            $title = esc_html($post->post_title);
            $excerpt = esc_html(get_the_excerpt($post));
            
            return sprintf(
                '<div class="featured-post"><h2>%s</h2><p>%s</p></div>',
                $title,
                $excerpt
            );
        },
        'attributes' => [
            'postId' => ['type' => 'integer', 'default' => 0],
            'showExcerpt' => ['type' => 'boolean', 'default' => true]
        ],
    ]);
}

Disable Collaboration (if needed)

// Disable RTC for specific post types
import { addFilter } from '@wordpress/hooks';

addFilter(
    'sync.providers',
    'my-plugin/disable-collab',
    () => []
);
